A little order.
A lot of clarity.
Messy list in. Useful list out. Remove duplicates, tidy up the spaces and get everything into the right order.
Just a better list.
Your list stays in this browser tab. No analytics, cookies or stored copies.
Keep what matters.
Lose the repeats.
A calmer way to work with everyday lists.
Tidy up a reading list, organize product names or remove repeated keywords. Listora handles plain text, one item at a time. Nothing is sent to a server, and your work is not saved when you refresh.
- 01
Choose the right separator
Use line breaks for most pasted lists. Comma, semicolon and tab modes split at every occurrence of that separator. This is not a CSV parser: quoted commas are not treated specially.
- 02
Define what counts as a repeat
Trim removes whitespace at the start and end of each item. Ignore case treats Pencil and pencil as duplicates; the first spelling is kept. Interior spaces and accents are preserved.
- 03
Finish in your own format
Natural sorting puts Item 2 before Item 10. Numbering follows sorting, then your chosen output separator joins the result. Copy it or download a UTF-8 text file.
Before you tidy up.
Does Listora save or upload my list?
No. The tool processes text in your browser without network requests or browser storage. Save your result before closing or refreshing the tab. Your browser may independently restore form fields.
Can I undo a cleanup?
Your original input stays in the Before field. Change any setting to recompute from the original, or copy it before you use Clear or Try example, which replace the input.
Why do some similar items remain?
Deduplication compares complete items. Interior whitespace, accents and punctuation are preserved, so “to do” and “to-do” remain different. Enable Trim item edges and Ignore case when you want those normalizations.
Is there a size limit?
The tool accepts up to 1,000,000 characters and 50,000 input items per operation to keep the page responsive. Larger inputs show an error rather than silently truncating your list.
